AIR GUN.

APPLICATION FILED MAR. 6, I9I9.

Eat-@uuid July 8, 1919.

ATTORNEY ported by a in 30 so that the nose 23 can swing toivar and awayfrom the plunger 21. suitably to engage with the recess 22 when inregistration therewith, and is held in such engagement with the plunger21 by means ofthe spring plunger 31.

The bulb 14 tends normally to assume the distended osition so as to drawair inwardly through t e barrel l0 and after the valve 21 has beenclosed by raising the lunger 21 and locked by the trigger mem er 2l thecompressing of the charge of air is effected by means of a block 32 thatis mounted on a lever 33 that is pivotally connected b its rear end withthe stock-11 by means o the pin 34. For convenience in holding thecharge in the compressed 0r loaded condition I provide a catch 35 forreceiving and engaging with thefree end 36 of the lever 33.

A novel feature of the air gun structure described in use is that theexpansive qualities of .the rubber bulb, because of which when thepressure on the bulb is released and the walls are free to do so theyopen out and thereby-draw in the fresh charge of air for compression,may be utilized at the same time for drawin the projectile into thebarrel, and the mec anism described is adapted for permitting this to beconveniently done.

One way of doing this would be to release the latch and at the same timehold the compression lever momentarily in the compressin position. Uponrelease of the lever the bu b will open and in so doing will force thelever outwardly and simultaneously will draw in a fresh charge of airthrough the barrel, and a projectile positioned at the mouth of thebarrel will be drawn inwardly to the proper loaded position by theentering charge of fresh air.

Thus the lever structure described provides means for controlling thedrawing in of the fresh charge of air and of controlling loading of theprojectile in the barrel.

I claim as my invention 1. An air gun having a barrel, an air chamber,and a collapsible tube connectin the said barrel and chamber, means forco lapsing the said tube comprising a member having a movement in theradial direction relatively to the said tube, the said member 2. An airgun having a barrel, an air chamber, and means of tubular form connectinthe said barrel and chamber, the said air chamber being in the form of abulb of elastic material, means for compressing the said air chamber,and means m the form of a lever for controlling the discharge from thesaid chamber.

3. In combination in an air gun, a stock, a barrel mounted on the saidstock, a rubber bulb seated in the said stock, a rubber tube connectingthe said bulb and barrel, trigger operated means for compressing thesaid tube, and means forncompressing the said bulb.

4. In an air gun having a barrel, an air chamber, and a collapsible tubeconnecting the said barrel and chamber, means for collapsing the saidtube comprising a member having a movement in the radial directionrelatively to the said tube and having one end adapted to .engage withthe said tube, the said y one end being equipped with a cushioncontacting` pad of rubber of appreciable thickness.

5. An air gun constructed and arranged to draw the projectile inwardlyalong the barrel to the loaded position simultaneousl with the drawinginwardlyof the res charge of air, comprising a barrel, a bulb havingexpansive walls connected to the said barrel, and a lever serving asmeans for compressing the said walls and for controlling the expansionthereof.

6. An air gun comprising a barrel, a bulb, a collapsible tube connectingthe said barrel and bulb, and devices for collapsing the said tube, thesaid devices comprising a moving member for contacting with the saidtube and having a movement in a radial direction relatively thereto.

7. An air gun as described in claim 2, and the said means forcontrolling the discharge from the said chamber being provided with atrigger. i
